What is Micro Injection Molding?
Micro injection molding is a specialised plastic injection molding technology for producing extremely small and intricate components, usually in low-gram weights. The process involves the injection of molten thermoplastic into microscopic moulds using high pressure.
The technology is applied in cases where conventional molding techniques fall short of delivering the required accuracy and detail, such as in implants, microelectronics, and precision equipment.
How Do Our Micro Injection Molding Services Work?
Our micro injection molding operations are strictly controlled from start to finish for accuracy, consistency, and high-quality standards. All phases are carefully designed to cater to the requirements of micro-component manufacturing.
1. Design and Feasibility Analysis
The initial step involves the examination of component design, materials, and the feasibility of production. We confirm that the design is appropriate for the process of micromolding.
Also, we check whether there are any design issues (flow, tolerance, among others) before proceeding further. This ensures higher quality and risk management.
2. Micro Tooling and Mold Design
Selected thermoplastics are prepared in order to obtain appropriate material flow during the injection molding process.
We monitor moisture level and temperature to prevent problems such as voids, bubbles, or degradation.
3. Material Preparation
The injection molding process involves injecting material into molds using sophisticated machinery, which can perform injection in small volumes under specific pressure and velocity.
We control injection parameters to accurately fill micro cavities. It will provide consistent geometry and surface finish of the product.
4. Micro Injection Process
We inject molten material into the mold with precise machines that can inject small volumes at a certain pressure and speed.
We carefully control injection conditions to fill micro cavities precisely. This ensures consistent geometry and surface finish of the product.
5. Cooling and Solidification
Even cooling is used to maintain accurate dimensions and to avoid deformations.
Also, efficient cooling channels and cycles are designed. It will improve the uniformity and stress levels of parts.
6. Quality Assurance and Testing
The inspection process involves precision measuring techniques to test geometrical and mechanical characteristics.
We comply with strict quality guidelines and a documentation process.
